Except where noted, everything here applies to both Firefox 116 and the Firefox 115.1 ESR. Firefox 115 is the current ESR so, going forward, only fixes will be backported to the Firefox 102 ESR.

Bug Fixes

• Users could access private browsing even when it was disabled by using the command line option. This was fixed in bug 1797806. This is not fixed on the ESR. We're looking into it.

Special Notes

There is one more planned release of Firefox 102 ESR, and then it will go out of support on September 26, 2023. Users will then be automatically upgraded to the Firefox 115 ESR.

If you need to prevent upgrades for any reason, you can use the new AppUpdatePin policy.
